<p>A process for producing a vulcanized rubber composition that includes S-(3-aminopropyl)thiosulfuric acid, a rubber component, a filler, a sulfur component, and a vulcanization accelerator,
the process comprising the following Steps (A), (B) and (C) ;
(A) : a step of kneading S-(3-aminopropyl)thiosulfuric acid having a median diameter (50%D) of 10 µm to 100 µm, a rubber component and a filler,
(B): a step of kneading the kneaded mixture obtained in Step (A), a sulfur component and a vulcanization accelerator, and
(C) : a step of subjecting the kneaded mixture obtained in Step (B) to thermal treatment.</p> |
